A fox after crossing a river got its tail entangled in a bush, and could not move. A number of mosquitoes seeing its plight settled upon it and enjoyed a good meal undisturbed by its tail. A hedgehog strolling by took pity upon the fox and went up to him:"You are in a bad way, neighbour," Said the hedgehog; "Shall I relieve you by driving off those mosquitoes who are sucking your blood?""Thank you, master hedgehog," Said the fox, "But I would rather not.""Why, how is that?" Asked the hedgehog. "Well, you see," Was the answer, "These mosquitoes have had their fill; if you drive these away, others will come with fresh appetite and bleed me to death."
